Blade Tensioning
proper blade tension reduces the risk of blade
breakage and improves cutting performance.
To correctly tension the blade:
1. disConneCt BAndsAW FroM poWer!
2. open the upper wheel door, and raise the
blade post and upper blade guide assembly
to the highest position.
3. Check the side-to-side deflection of the blade
midway between the upper blade guide and
the table. the proper amount of deflection
should be approximately
3 ⁄
8
" when moderate
pressure is applied (see figure 33).
Note: The quickest and easiest way to check
blade tension is to use the Model H5408
Blade Tensioning Gauge (refer to
Page 34)
NOTICE
To prolong blade life, release the tension on
the blade if the machine will be idle for an
extended period of time.

figure 33. Blade deflection when correctly
tensioned.
Always disconnect power
to the machine when
changing blades. failure
to do this may result in
serious personal injury.
All saw blades are dan-
gerous and may cause
personal injury. To
reduce the risk of inju-
ry, wear heavy leather
gloves when handling
saw blades.
Blade Changes
To replace the blade:
1. disConneCt BAndsAW FroM poWer!
2. open the upper wheel doors.
3. release tension on the blade by rotating the
tensioning handwheel.
4. put on heavy gloves, then slide the blade off
the upper and lower wheels.
5. install a new blade in reverse order. Before
returning the saw to use, be sure to properly
tension the blade, check the tracking, and
break it in.
Note: Make sure the teeth are pointing down
toward the table. If the teeth will not point
downward in any orientation, the blade is
inside out. Remove the blade and twist it right
side-out.
4. Make small adjustments to the blade tension-
ing handwheel, then rotate the top wheel
by turning the gearbox pulley several times
before checking the blade deflection again.
repeat this step until you are satisfied.
Note: Make sure the blade tracks next to, but
not touching, the upper wheel flange as you
rotate the upper wheel by hand.
5. Close the upper wheel door and reposition
the guide post.
